Does the rotation of the earth affect your walking/ running performance and speed?

No. It's a question of scale.

The only thing I'd like to add is that the Coriolis effect is NOT what determines the way the water goes down a drain. The coriolis effect only works on large scales, and with water in a sink, there are other forces at work that are much larger. Sinks are designed to have a miaximum exit flow rate, and anyone that says 'but I've seen it done on the equator' has been scammed. Not only is the equator museum in Ecuador not on the actual equator, but it all depends on how you put the water in. So yep, the coriolis effect does indeed describe the larrge scale movement of air currents but not the water in a drain

the Coriolis effect does NOT effect water gong down drains, it only effects large scale models. and no the rotation does not effect you. the conservation of energy comes ito action. not only is the earth moving but so is everything on it and all the air. a comparision would be moving on a train. despite the bumps (which are outside factors) you can still move, run etc with the same ease even if its travelling in the opposite direction than youre, say, walking.

The earth is so huge that it wont effect t something as small as a human. It does effect weather systems hugely.

Trying to live on a small rotation thing, eg Space Station would be tricky. Your feet would experience higher gravity than your head, your head would go 'faster' over the ground than your feet walking against the rotation and visa versa are are couple of the disorienting effects

Everything on the surface and the environment at the surface in which everything is immersed for the most part all stick to the surface and thus turn at the same rate and are unaffected. To a minor degree, the spinning force does affect fluids, e.g. water swirling around a drain, known as the coriolis effect. (If you are thrown out of a spinning barber's chair, do NOT let the barber blame it on that.)

yeah i've always wondered that!

The tornadoes and winds, spin the way they do as a result of the rotation of the Earth and not the other way round.

Amazing though isn't it- the Earth is travelling several thousand km an hour and is spinning at several hundred miles an hour and we don't feel a thing!

Well, it gets dark when the earth has rotated enough to spin my bit so its not facing the sun anymore. I tend to run slower when I can't see where I'm going. It's cooler at night though so I can run longer at a particular speed witout overheating so much.

Speed is measured relative to a "stationary" object. The earth is moving relative to the sun and rotating around its own axis which is moving relative to the galaxy and so on. Speed is measured relative to the earth so regardless of which direction you are running the speed relative to the earth remains the same.

Circumference of Earth at equator = 24,902 miles.

Earth makes one complete rotation in ~24 hours.

24,902miles/24hours = ~1037 miles/hour.

Multiply by the cosine of your latitude to get the speed of rotation at your location.

My latitude is ~42 °, so it is spinning at the rate of 1037(.743) = ~770.5 miles/hour.

Last week I started running (with my little laptop and speedometer). I noticed that my speed was approximately 780 miles per hour—except when the storm had me going in circles—but when I turned around to head home, my speedometer read, '0'. Am I actually running -10 miles per hour? Maybe that's why I cannot seem to get home. Help me! Is this what they call limbo? ♪♫

the effect that controls the ease of your movement in a centrifuge or the spinning of water in a drain is all caused by the coriolis effect. everyone on earth experiences the coriolis effect, but it is so subtle that we cannot feel it. google or yahoo the coriolis effect. it will explain it more.

No.Remember that when the earth is rotating there is no effect this is due of the gravity that is around us and above us.
